6. Abstract

We propose to use the deep ACS images obtained by the Great Observatories Origins
Deep Survey (GOODS) in combination with a sample of ~300 spectroscopically
identified galaxies with 1.4<z<2.6 (formerly known as the ``redshift desert'') to
investigate the dependence of galaxy morphology on environment, kinematics, chemical
abundances, UV emission and absorption line strength, stellar and dynamical mass,
and galaxy-scale ``superwind'' activity. To determine these physical properties of
the galaxies, we will supplement the ACS data with rest-frame UV spectra of the
entire sample, rest-frame optical and IR images of a large portion of the field, and
near-IR spectra of H-alpha emission of a subsample. Thorough analysis of the ACS
images will allow us to test the sensitivity of existing morphological analysis
tools to physical properties of the galaxies, and to develop new metrics if the
existing tools do not prove to be the most relevant.
